I found a cave that teleports you into solid rock. Luckily, it was not lethal, but Im pretty sure it shouldnt do that. Devs, if you want the location, Ill PM it to you.
<Marcher Lord> Dogs! Oh god, please give us DOGS! There are those who press on with the ardor of beer, and those who are faint with thirst.
Also relating to caves but not really to this problem, whenever I enter one I see the ground texture of that outside the cave. I'll see forest, plants where they were, and even claims (though the claims don't work). No cave walls, no cave terrain texture, nothing. After groping around for a bit and hitting the invisible walls it'll fix itself and I'll see the cave's true graphic. Seems to fix with lighted torches and fires too.
Yes, I am aware; there was a bug in the mapgen, it seems, so all cave entrances outside the center supergrid seem likewise bugged. I just haven't gotten around to repair it yet.
